- jlgaddis 8y agoThat isn't a reserved/private network either.
- walrus01 8y agoI shake my head in bewilderment when I see stuff like this - just why would people make things harder for themselves. I very highly doubt that they are so large that they ran out of IP space in the enormity of 172.16/12 to encompass all of their OSPF/BGP router-id /32s and individual /30 OSPF router-to-router links.
- majewsky 8y ago> enormity What's enormous about an IPv4 /12? :) When the German army requested an allocation of IPv6 address space, they were given a /28, but complained that 2^100 IPs is not enough for them and they actually need a /22.
- walrus01 8y agoWell it's not so enormous, but it's also accompanied by 10/8 and 192.168/16. Many networks use some combination of all three internally for different purposes.
- mastax 8y agoThats mind boggling... I'd like to read that reasoning about that! (I'm sure there's some German-language publication somewhere...) Did they want each bullet to have a /64?
- walrus01 8y agoI have both a /29 and a /32 of v6 space, and unless my ASN achieves total global domination on a scale never before seen by humankind, it should last a good long time. :-)
- namibj 8y agoWell, bullets might move between routers, so they might change the Layer-2 network they are on, and thus might need their own independently routable address. Afaik it is bad practice to route anything smaller than a /64.
